ALKALINE LUBRICANT FOR OILING GUNS.

SPECIFICATION forming part of Letters Patent No. 768,835, da ed Augus30, 1904.

Application filed September 22, 1903.

T (LIZ w it/mt it may concern.-

Be it known that I, JosErH G. IVILD, of New Haven, in the county of NewHaven and State of Connecticut, have invented a new and usefulImprovement in Alkaline Lubricants for Oiling Guns; and I do herebydeclare the following to be a full, clear, and exact description of thesame.

My invention relates to an improvement in that class of oils orlubricants used on guns, the object being to produce a non-aqueouslubricant which shall neutralize the acid residues left after firingsmokeless powders, and so prevent rusting or corrosion.

IVith these ends in view my invention consists in a non-aqueous alkalinehydrocarbon lubricant.

My invention further consists in certain details, as will be hereinafterexplained, and pointed out in the claims.

In carrying out my invention I employ a fixed or non-volatilehydrocarbon lubricant, such as Vaseline or some other mineral oil. Torender this alkaline, I introduce into it an alkali, such as ammonia,which might be replaced by some other alkali, such as caustic soda orcaustic potash. If ammonia is employed as the alkali, I shall preferablyuse an alcohol solvent for it, such as glycerin,'which may be replacedby some other alcohol or even by some non-alcoholic solvent, such asaldehyde, ketone, or quinon.

While I do not limit myself to any particular way of making my improvedalkaline lubricant, I have secured excellent results by passingammonia-gas into commercial glycerin. Then when the glycerin has becomestrongly charged with the ammonia gas, whether to the point ofsaturation or otherwise, the ammoniacal glycerin is mixed with ahydrocarbon lubricant in the'proportion of one part of the ammoniacalglycerin to five parts of the Vaseline, though these proportions may bevaried according to the strength Serial No. 174,205. (No specimens.)

and character of the ingredients and to the way in which the completedlubricant is to be used. Ordinarily the alkaline lubricant thus producedwill be used in the same way that any lubricant or gun-oil is used. Incase the gun has been fired with smokeless powder and 5 0 then oiled theacid residues remaining on the surfaces of the gun will be so completelyneutralized by the alkaline character of the lubricant that there willbe none of that rusting or corrosion which results when a gun is firedwith smokeless powder and then oiled by the use of the ordinarylubricants, which will not prevent corrosion or rusting, because they donot neutralize the acid residues remaining on the surface of the gunafter it has been fired with smokeless powder.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. Anon-aqueous alkalinelubricant for neutralizing the acid residuesleft on the surfaces of guns after firing smokeless powder in them andso preventing corrosion and rust, the said lubricant having an alkalinereaction and con sisting of a fixed hydrocarbon lubricant mixed 7 withan alcohol saturated with ammonia which is retained in the'solutionthrough the presence of the alcohol.

2. A non-aqueous alkaline lubricant for neutralizing the acid residuesleft on the surfaces of guns after firing smokeless powder in them andso preventing corrosion and rust, the said non-aqueous lubricantconsisting of a hydrocarbon lubricant mixed with glycerin charged withammonia-gas which is retained in the soso lution through the presence ofthe glycerin.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
